For an integer n≥3 and any positive number ɛ, we establish the existence of smooth functions K on ℝn∖{0} with |K−1|≤ɛ, such that the equation \({{ \Delta u + n (n - 2) K u^{{{{n + 2}}}\over{ {{n - 2}}}} = 0 {{{{\rm{ in}}}}} {{{{\mathbb R}}}}^n \setminus \{ 0 \} }}\) has a smooth positive solution which blows up at the origin (i.e., u does not have slow decay near the origin). Furthermore, we show that in some situations K can be extended as a Lipschitz function on ℝn. These provide counter-examples to a conjecture of C.-S. Lin when n>4, and a question of Taliaferro.
